MACHINE FOR CASTING TYPE.

Specification of Letters Patent.

Patented Sept. 12, 1905.

Application filed ly 5, 1904. Serial No. 215,450.

To all whom it may concern:

Be it known that I, FRANcIsWILLIAM H nws, a subject of the King of GreatBritain, residing at 88 Browning road, Manor Park, in the county ofEssex, England, have invented new and useful Improvements in Machinesfor Casting Types, (for which I have applied for a patent in GreatBritain, No. 16,068, bearing date the 21st of July, 1903,) of -which thefollowing is a specification.

The object of this invention is to so construct the molds wherein tocast the types and to so arrange mechanism to open and close said moldsthat any convenient number of types of the same or various sizes andsorts may be cast simultaneously at one operation of the machine; and afurther object of this invention is to use mechanism whereby types socast may have their tailings removed and the types so finished may beautomatically collected side by side and close together ready to beplaced on the type-founders stick for assortment, to attain which Iarrange my improved molds and mechanism for opening and closing same andmechanism for cutting off the tailings and for delivering and eollect--ing the types, substantially as described, by the aid of theaccompanying drawings, in whieh Figure 1 is an end elevation of mymachine, showing the principal mechanical parts there in in positionwhen the cast types are being delivered from the molds, and Fig. 2 is afront elevation of the same. Fig. 3 is a front view of my improved moldswhen closed and part of the mechanism for operating the same, and Fig. Ais a similar view when the molds are open. Fig. 5 is a longitudinalsectional elevation of the type-collecting table at the front of mymachine, and Fig. 6 is a plan of same. Fig. 7 is a plan of atype-holder, and Fig. 8 a cross-section of same. Fig. 9 is a side viewof the complete machine; and Fig. 10 is a side elevation of the machineupon a reduced scale, illustrating the mechanism for causing the shaft Kto rock and for operating the trimming-knife J.

Similar letters and numerals of reference denote corresponding parts ineach view.

My improved molds within which are cast the types are made out ofhardened-steel blocks in the following manner: The upper part of eachsaid mold consists of the top and one side marked 11/ of the mold W, andthe bottom and opposite side marked m forms the other part of said moldwhen closed, as shown at Fig. 3. The parts 2/1 of the respective molds Hare secured to an upper carrier A, which is lixed to side arms B,carried on a cross-shaft I), which is supported on bearings, (notshown.) but fixed to bed-plate 7f of the machine. The lower parts m ofthe respective molds M are lixed to a lower carrier (J.

The upper carrier A may carry any desired number of parts m,corresponding to the number of molds M required, and combined theyremain a fixture to the side arms B. which latter simply rock orreciprocate. The bottom carrier C, with its respective mold parts mhowever, receives a lifting and lowering motion by being carried on thetop of two rods R, which have inclined or angular sliding parts Sbearing in inclined or angular slides or bosses s, which are made withthe frame part .3 of my machine. The rods R may be forced upward anddownward by means of cams r (see Figs. 1 and 9) or in any otherwell-known way, and such mechanism may receive its motion from the shaftW by means of a chain-gearc', and the arms B may receive a to-and-fromotion by means of a cam Q working on the driving-shaft \V, carried inthe frame x of the machine, and being pulled back by a spring 11.

At the top of each arm B, .l fix a plate or bracket 6*, (shown in dottedlines, Fig. 1,) which carries a rod 7/, extending from one bracket tothe other. At the front of the upper carrier A, I hinge, swivel, orpivot a number of matrix-bars l), and to the rod 7/ 1 fix or mount acorresponding number of levers E, the lower end of each of which comesincontact with the upper front part (1 of its respective niatrix-barD. Thebrackets I) also carry a shaft f", extending from bracket to bracket atalower level than the red I), and this shaft f" carries a number oflevers F corresponding to the number of matrix-bars l) and so arrangedthat at times the ends of adjustable screws f which are carried throughthe lower parts of said levers F, come in contact with the lower partsof the matrix-bars D. The top part of each lever F is formed with aprojection f. The brackets 5 also carry a shaft K, which extends fromone.bracket to the. other, and it has secured to it a continuous tappetKQwhich extends between the parts f 3 of levers F and the face of leversE. The shaft K is caused to rock by a lever 10, worked by aconnecting-rod 11, coupled to a. rod 12, which latter has a runner 13hearing in a fixed quadrant 14. (See Fig. 10.) As the arms B travel toposition for closing the molds M the runner 13 lifts the rod 12, and theconnecting-rod l1 lifts the lever 10, so causing the tappet in to pressagainst the respective ends f of the levers F, and when the arms B arein the position shown at Fig. 1 the tappets 75 press back the levers E,which press the top part d of the matrix-bars D, and so cause the lowerends of said bars to extend away from the upper parts m of the molds M.Each matrix-bar D has a matrix formed on its inner face, and when thearms B move to position so as to bring the parts m over the parts mclose up thereto, as shown at Fig. 3, the matrixbars D are caused toclose by the reverse action of the tappets it" coming in contact withthe projectionsf and causing the protruding inner ends of the screws f 2to press against the bars D at the same time the levers E are released,so that each matrix cl takes up its required position at the end of eachmold M, and the same are then ready for an injection of molten metal,which is forced through the respective nozzles Z from a melting-pot V bymeans of pistons and cylinders or pumps in a well-known mannerthat is tosay, the molten metal is forced through the nozzles Z and past suitablecheeks m into the molds M.

The matrix-bars D are held in position during the casting of the typesby the respective levers F. As the arms B return to position (shown atFig. 1) the parts m at once lower and the cast types m remain in theupper parts m of molds M, owing to the presence in each of the molds ofwhat is known as a pin-hole or drag, and the types so remain untilmechanically knocked out or delivered by a delivery-knife J, carried ina slide y" at the back of the upper carrier A. This knife J is forceddown by the same motion and at the same time as the levers E pressagainst the upper parts of the matrixbars D, so as to remove thematrices d from the types 00 and this action cuts off the tailings ofthe types m and at the same time causes the said types m to falllengthwise onto a chute G-that is to say, as shown at Fig. 10. The lever10 is coupled to a lever 15, fulcrummed at 16, and the lever 15 isconnected to the knife J by a rod 17. Therefore as the lever 10 lowersthe rod 17 also lowers and causes the knife J to act in the mannerdescribed.

On the chute G are arranged a number of channels 1, corresponding to thenumber of molds being used. The cast types fall therein in mannerdescribed, and they travel by gravity onto a reciprocating table X,containing a number of bridge-shaped holders w, the types 00 falling topositions between these holders, as shown at Figs. 5 and 6. The spacesbetween the holders .13 form the termination of the channels I. When thetypes 00 have so traveled by gravity onto the table X and taken uppositions between the holders w, the table X is caused to move to theright, and the bridge-shape holders 00 first pass over an inclined plateY, onto which plate the types 12 collect, and they are carried up thisplate by the sides of said holders and then onto a forked-shaped part 3of the incline Y, the holders w finally passing between said forkedshapepart and delivering the types close together and in line side by side,so that they may be finally collected upon the type-founders stick Q ina completed condition and ready for assortment. The table X isreciprocated in this manner at every operation of the machine by meansof a connecting-rod z, worked from an adjustable crank .2, carried on adriven shaft 2 worked from a pair of bevel-wheels 2 and at driven fromthe shaft W.

Having fully described my invention herein, what I claim, and desire tosecure by Letters Patent, is

1. In a type-casting-machine the combination of a number of moldsarranged by fixing the upper part and one side of each mold to an uppercarrier mounted on reciprocating arms, and the lower part and oppositeside of each said molds to a lower carrier supported on rods worked upand down obliquely by means of cams, said rods being supported on saidcams and guided by oblique bearings at upper parts substantially asdescribed.
